课前即兴演讲（通用12篇）
尊敬的老师、亲爱的同学们：
大家上午好!
亲爱的同学们，当你踏着晨光走进我们花园般的校园时，当你坐在干净整洁的教室里学习时，你是否想到老师、同学们为此的辛勤付出?
我们都渴望校园中能有郁郁葱葱的草地，都期盼在整洁干净的环境中学习、玩耍，都希望在舒适温馨的宿舍里进入梦乡。
可是却有同学不懂得珍惜这些美好的事物。请同学们放眼校园仔细看看——那洁白的墙壁被打上了鞋印、球印;桌椅上留着乱涂乱画的痕迹;水龙头开着，让水肆意的流失;美丽的草坪、花圃上留着无情的脚印;塑料袋、包装盒、果皮纸屑扔得满地都是，在其他同学午晚休的时候，宿舍楼内外高声的喧哗，打破了这一片宁静。这些现象与我们美丽、文明、和谐的校园多么不协调!
我们崇尚文明，我们都需要生活在干净、整洁、美丽的环境中，然而，为什么我们总把打扫、维护的希望寄托在别人身上?为什么总是毫不怜惜的践踏这片宁静与美丽?为什么总是逃脱作为_中一份子的责任?
同学们，立即行动起来吧!一片纸，我们捡起;一滴水，我们节约;一堆垃圾，我们打扫，爱一棵小树苗，保护一只小青蛙。为了我们的校园，做我们能够做的一切。“勿以善小而不为，勿以恶小而为之”。为此我向_中全体同学呼吁：创建清洁、文明的校园，需要你，需要我，需要我们大家共同的努力。让我们积极行动起来!让我们从现在做起，从身边的小事做起，加强自我约束，相互监督，争做保护校园环境的小卫士。
我的演讲完了，谢谢大家!
老师们、同学们：
大家好!
仰观宇宙之大，纵论古今名人，凡是功成卓绝之人，他们都有一个成功的秘诀，那就是坚持!
坚持是取得成功的必备素质。它犹如一条红线，贯穿了始终，是长久不变的意志表现。“骐骥一跃，不能十步;驽马十驾，功在不舍。锲而舍之，朽木不折;锲而不舍，金石可镂!”这句话充分说明了一个人如果有恒心，一些困难的事情便可以做到;没有恒心，再简单的事也做不成。
总览古今中外，大凡有成就的人，无不具有坚持的精神。《史记》这部鸿篇巨著被世人称之为“史家之绝唱，无韵之离骚”，可你知道，它是司马迁耗费了17年的时间，不顾宫刑的折磨，呕心沥血的杰作。更有李白铁杵成针，屈原洞中苦读，匡衡凿壁偷光，他们的精神印证了“贵有恒，何必三更五更睡，最无益，只怕一日曝十日寒”的真理。他们用行动告诉我们，只要有滴水穿石的精神，持之以恒，成功不会遥远。英国首相丘吉尔在面对德国法西斯的疯狂进攻时，就曾对他的国民说过：“不要屈服，永远不可屈服。”这不但是一句振奋人心的豪言壮语，也是他最重要的人生总结，体现了他坚持到底的精神。大家都熟悉愚公移山的故事，愚公之所以能够感动天帝，移走太行、王屋二山。正是因为他具有锲而不舍的精神。可见，成功离不开坚持。
学习也一样，学习不是一朝一夕的事情，学习中感到枯燥在所难免，很多人都因半途而废，而最终一无所获或收益甚少。不少同学知道学习很重要，但是学习累了，作业多了，就失去学习的兴趣，就变得懒惰。究其根本，就是缺乏持之以恒的精神。学习需要恒心，需要持之以恒。在任何条件下，都向着自己的奋斗目标坚持不懈地努力，永不退缩。如果在学习中总是知难而退，半途而废，那么就永远不会取得好成绩。在学习中，我们要坚持把每一课学好，坚持克服每一个困难，坚持地朝自己定下的目标前进，总有一天可以把铁杵磨成针，把金石打磨穿。学习很苦，却又不苦，只要有坚持不懈地决心，那些学习中的困难也不过是脚下一粒石子，如果遇到困难就放，那困难就是眼前的高山。
蜗牛坚持着爬上金字塔顶得到了雄鹰的世界;乌龟坚持获得了兔子的荣誉;愚公坚持而让山移。只有坚持，才能开启成功的大门，我们要学有所成，就要坚持学习。同学们，学习中就要有毅力，有恒心，相信“锲而不舍，金石可镂。”让我们站在此刻的起点上，坚持到底，永不言弃。珍惜初中剩下的时光，用今天的刻苦，铸就明日的辉煌!
谢谢大家!
敬爱的老师，亲爱的同学们：
大家早上好!
今天我讲话的主题是“有始有终，定能成功”。古希腊哲学家苏格拉底曾经在中学当教师，有一天他对班里同学说，我们来做个甩手游戏吧。游戏很简单，就是把手使劲往前甩三百下，再往后甩三百下，但要求每天都这样做。同学们纷纷说这个游戏容易，保证能做好。一个星期以后，苏格拉底问同学们游戏完成得怎么样?同学们全都举起了手。一个月以后，当苏格拉底再做统计时，全班仍有百分之九十的同学在坚持做。一年以后，当苏格拉底在课堂上再次向大家了解情况时，只有一位同学举起手，他就是后来成为大哲学家的亚里士多德。亚里士多德在自己的学习和生活中，凭着这种持之以恒的精神，自觉锻炼自己的意志，终于在哲学领域取得了前所未有的成就，其哲学思想直到现在仍然放射着智慧的光芒。
同学们，这个甩手游戏从动作上看很简单，但每天坚持，却是一件不容易的事，需要持之以恒的精神。这个故事告诉我们，做事情要有始有终，绝不能半途而废，如果我们能养成这样的好习惯，就一定会取得好成绩。人们常说，在科学之路上没有平坦的大道，只有敢于在崎岖的小路上不断攀登的人，才能到达希望的顶点。让我们认准自己的努力目标，坚持不懈地努力，不断地鼓励自己，这样我们就会体验到成功的喜悦和收获的快乐。
最后，我送给大家一句法国生物学家巴斯德的名言：告诉你使我达到目标的奥秘吧，我的力量就是我的坚持精神!
谢谢大家!
Dear Teacher, my dear students:
Good morning!
I come from class ? grade ?, my speech is entitled "I love my school."
Towering at the foot of the iron roof temple, at the Trans-North and the South side of Xiangfan, in the post-rolling river foreshore, is located forward of a Beauty School - Middle School Maoba.
Dawn, the night has not yet started,grass sweet to fall asleep, and the birds have not woke up from their sleep, the entire campus at the morning mist in the diffuse, like the mythology of the Temple. At this time, you see that white at a distance of teaching buildings, will be strange to see a white fog with wind around his waist in the Academic Building.
Gradually opening night, the morning mist at the vast expanse of whiteness receded, at the flow. At this time, there have been at the morning mist of vague shadows, one, two ... five ... ten ... ... in droves, accompanied by cheerful laughter, walked into the campus.
I do not know when, brilliant red Zhaoxia a half of the sky, soft colors will sprinkle campus. Little tree woke up, dipped in dew; wildflowers awake, able to smile; birds awake, showed voice, toward the blue sky.
I love our school! I love our teachers!
Needless to say, money is not very important, but very very important.
If there is no money, I can’t use this microphone to speak to you and we can’t have such a room to hold such a competition. Without money, we can’t study in such a schoolyard. Without money, we can’t live in such a hometown. Without money, we can’t have such a motherland. On the other hand, If there is no money, you don’t need to bear my speech about money now.
Most of us have dreams about the future, dreams of having a good job and making much money. Surely someone has thought at times “If only I had a lot of money, I could be the happiest person in the world.” In fact it’s the main mistake that people make about money.
However, is money the road to happiness? Not really! Many people work every day, work overtime, work weekends to make a lot of money. Are they happy? No. They are too busy making money. Meanwhile, their personal lives, if they have any, fall apart. They have no time to form or to maintain friendship. They even lose the abilities to relax and to enjoy themselves. Enjoying means taking things, taking time to see, to hear, to taste, to smell, to feel. They do not take time to do this. They say: “I’ll do it when I have enough money to retire” then they find that it is too late.
Why we usually make such a mistake and even more mistakes? Activists say it is because of money itself. They think money has changed many things. For example, they think money has changed our way to measure someone’s value in the society. They even regard money as the source of evil. Also, they hate money, but they are wrong, completely wrong.
In my opinion, it is unfair to money. Money is a tool. Well, there’s no denying that we do something harmful with money. But we can’t say money is the source of evil. Just like a hammer, we can use a hammer to kill someone, but can we say a hammer is a devil? It is the same with money.
Money is neither good nor bad itself. It is a mirror, a perfect and important mirror, and a mirror that reflects both the darkness and the brilliance of humanity. In other words, all depend on us.
So, my fellow students, ladies and gentlemen in the future, ask not what we can do for money, ask what money can do for us, ask what money can do to show the brilliance of humanity. Because, we have the future; we are the future.
Every one of us,rich or poor,should at least have one or two good friends.My friends will listen to me when I want to speak,will wipe my eyes when I cry,will take care of me when I am sick,and my friends will go together with me side by side through this journey of life.
As students,we could share more time with our friends.The friendship in our young hearts is pure,fresh and simple.I often feel very lucky to have a lot of good friends.Especially when I had Justin as one of my best friends.Justin was my English teacher from the USA.I met him in 1996 when I was a student who could only speak very little English.Justin was a vivid young man with a bright smile on his face,and he always had his special way to make the class active and attractive.He taught us English by telling stories,playing games,singing songs,and even dancing.I could still remember very clearly that one afternoon when we fin-ished our class,we went to some other classes to sing songs for them,just like what people do in the states on Christmas Eve.It was so interesting and unforgettable.Justin was an excellent teacher,because he taught us not only how to study English well,but also the way to find out the beauty of the world and the way to be angels to others' lives.I know there was friendship and pure love in our hearts.Facing this valuable emotion neither nationality nor age was important,the real importance lay in faith,under-standing,and care.Justin is the best friend I have ever had,and I know I will cherish those days of staying together with him as the best part of my memory.
Friendship is a kind of treasure in our lives.It is actually like a bottle of wine,the longer it is kept,the sweeter it will be.It is also like a cup of tea.When we are thirsty,it will be our best choice,but when we have enough time to enjoy ourselves,it is also the most fragrant drink.
Only mother love is true love .It's gives everybody everything in all his life ,When you are still a baby ,mother takes good care of you as much as possible.In your waking hour she always holds you in her arms.When you are ill,she stop her work right now to look after you day and night and forgets about herself.When you are growing up day by day,she feels very happy.When you are old enough to go to school,mother still looks after you all the time.On cold winter days,she always tells you to put on more clothes.She always stands in the window waiting for you back from school.When you are hurry to leave home for school for breakfast ,she feels worried about you at home.She usually knows about your study and spends much money on your school things .When you do well at school .you will see the brightset smile on her face.
we are the saint on earth, and should treasure our love, but we should know how much is good and where to stop. since there's no ever-lasting banquet, nor is there an endless love story, we should take the gains and losses of love with perfect composure. there's fragrant grass in every corner of the earth, and you can always find your love in this world.
Mother is ailways ready to give everything she has to her children ,not to receive.
What true love that is in the world !We will remember Mother love forever .
尊敬的各位领导、老师，亲爱的同学们：
水是大地的血脉，它滋润着崇山峻岭，灌溉着良田;水是一切生命的源泉，它养育着飞禽走兽，哺育着花草树木;水是人类文明的摇篮，在人类文明的发展，因为水环境的变化，导致一个国家一个民族盛衰变迁的例证举不胜举。源远流长的中华文明，也正是依存长江、黄河等母亲河的支撑，而发展下来的。
长期以来，人们普遍都认为水是“取之不尽，用之不竭”的。其实我们地球虽被称之为“水球”，但其淡水储量却是少之又少!水资源并不是“取之不尽，用之不竭”的，水将成为21世纪威胁世界和平影响社会发展的障碍。
所以在全球的水资源危机日益严重的情况下，节约用水便成为每个公民应尽的职责。尤其在中国，水资源的人均占有量并不丰富，淡水资源不到世界人均水量的1/4;地区分布并不均匀，年内变化莫测，年际差别非常之大，每年受旱农田32亿亩，约有5000万人和3000万头牲畜面临水荒。再加上污染，使水资源更加紧缺，所以人们更应该节约用水。如果大家能够从我做起，从现在做起，从身边做起，牢固树立节约意识，从节约一滴水、一粒米、一度电、一张纸入手，把节约落到实处。如果这样，对学校来说，那将是一笔可观的财富，对于我们这个13亿人口的大国来说，那就是一个惊人的数字。
节约是一种美德，节约是一种智慧，节约更应该成为一种习惯和风气。建设节约型社会需要全社会的共同参与和共同行动，找回失去的节约意识，从身边的点点滴滴开始，持之以恒，在建设节约型社会中，将节约这个“传_”进一步发扬光大!
只要大家都注意节约用水，水荒才会远离我们，我们的生活才会安定、和谐;环境才会优美、舒适。同学们明白这个道理后，一定要自己身体力行才行!什么叫爱国、爱校、爱家，不是天天喊在嘴上，而是要落实在行动中。如在家中、在学校节约用水这就是爱国、爱校、爱家的具体表现。
作为当代的中学生，我们应该弘扬中华之美德，节约身边之滴水。
莫让人类的眼泪成为地球上最后一滴水!
谢谢大家!
大家好!
有一幅对联是这样写的，上联是：“校园安全，你管、我管，大家管才安全，下联是：事故隐患，你查、我查，人人查才无事”。横批：安全是天!一句“强化安全意识，提高避险能力”就显得尤为重要!
安全，对于我们学校来说是个老生常谈的话题，也是一个永恒的主题。安全是大事，是关系到千家万户的大事，是利在当前，功在千秋的大事。安全是学校工作的前提，没有平安和谐的良好氛围，就难以有正常的教学秩序，就难以提升教学质量。因此，学校领导深刻体会安全的重要性，切实把安全工作落到实处，让安全工作取得实实在在的效果。
在3.11日本强震海啸中，宫城县户仓小学，距离海岸仅仅100米，学校共有108个学生，有一个孩子那天没来上课，在校孩子们全部生还。当天海啸前首先发生的是地震，孩子们都躲到桌子底下，紧接着，孩子们跑到学校操场，然后爬到学校后面的山上。他们是按照日本应对海啸的标准流程操作的，这是每一个人都会反复演练的疏散方式。在日本连幼儿园的孩子都要进行安全逃生演练，并作为法律规定。强烈的安全意识和熟练标准的安全演练在关键时刻能挽救人的生命。
或许，你会认为安全问题离我们很远，有的同学心里可能会说：“我很安全啊!没必要这样大张旗鼓地教育我吧?”其实不然。想想自身的行为，不也有许多安全隐患吗?一至十班的车区在东面有个陡坡，可有的同学骑着车就冲下来，在你很拉风的同时有没有想过如果先着地的不是车轮会怎样?以前看见有同学在操场上点火玩，难道你还真的以为会“野火烧不尽”吗?大课间有同学在排球场里踢球，在你撩大脚的时候有没有想过球砸到人群里会是怎么个后果?有些同学为了少走几步路，跨越马路防护拦;看到路上车辆不多，等不住就匆匆横穿马路。有些同学上下楼梯偏靠左边行走，或在楼层的楼梯、走廊内追逐、奔跑、打闹、玩耍，从而导致相互碰撞而受伤。血的教训不能再有一次，悲剧不能重演，为了预防此类事件发生，我们一定要树立安全意识，掌握一些必要的卫生知识、安全防卫知识及应急避险技能，从而提高自我保护能力。
20xx年3月28日是第22个全国中小学生安全教育日，主题是“强化安全意识，提高避险能力”。在安全日来临之际，我们将要开展安全知识宣传、安全疏散演练、“学校安全隐患我发现，家庭安全隐患我排查”活动，同时我们更要将安全意识和行为作为一种习惯进行养成。我们需要养成的安全好习惯有：遵守交通规则;不玩火;放学次序离校;不急追猛跑;上下楼梯右行礼让;增强安全自护意识;不做危险动作、游戏;离家离校要向家长或老师打招呼。
同学们：当你在谋划着新的一天的学习和生活时，是否想到了安全?当你在聆听奉劝时，是否想到它是用血的教训凝成的?当你对别人提醒或忠告不以为然的时候，是否想到因为一时的疏忽，一次的失误，可能会给自己带来痛苦，给家人蒙上阴影，给社会带来负担，给国家造成损失?避险不是辟邪，是需要我们加强注意来提高防患意识的。最后，作为读书人，让我们把这句“安全无小事，隐患就是事故”记在心中。我的演讲完毕!
if you want to be more successful, if you want to have and do stuff you never done before then i’m asking you to invest in you!
someones opinion of you does not have to become your reality.
you don’t have to go through life being a victim. and even though you face disappointments, you have to know within yourself that ‘i can do this, even if no one else sees it for me, i must see it for myself!’
no matter how bad it is, how hard it gets, say to yourself, i’m going to make it!i wanna represent an idea. i wanna represent possibilities. some of you right now, you wanna go to the next level. you wanna be a civil engineer, you wanna council, you wanna be a doctor.listen to me: you can’t get to that level. you can’t get to that level until you start to invest in your mind
i dare you to invest in your mind.
i dare you to invest time.
i dare you to be alone.
i dare you to spend an hour alone to get to know yourself.
i challenge you to get to a place where people do not like or do not even bother you anymore. why? because you’re not concerned with making them happy anyway. because you’re trying to blow up. you’re trying to get to the next level. because you’re investing in your mind.
if you’re still talking about your dream and your goals but you have not done anything just take the first step.

Ladies and gentlemen ,thanks for raising your attention .Today I’ll give you a speech named “global citizenship begins at home”.
Being received by many international organizations just like OPEC ,WTO ,all of us get closer contact with other parts of the world ,so that we should not only deal with the native citizenship well ,but also global one .
No doubt “Kyoto Protocol” is a model of assembling abilities all over the world to administer and green-house gas pollution .It’s beyond the effort made by politicians and environmentalists only ,and requires all men to attend it .Face to such issues ,we are no more than a person who comes from a certain city even a specific country ,but a global citizen that everyone should say it proudly .
Besides ,from Madam Curies who argues that science and technology should not be limited by national boundaries .Progreis never a nationality’s or a country’s progre,it need all to avail from it .Creating or spreading science and technology ,together with direct economic support ,bridges the gap between one area and another ,which in order to help a creature as same as ourselves or just because of deep sympathy .Thus a person exists as individual ,as well an undivided part of human beings all over the world .Even though what we could do may be negligible ,doing something without regret is the necessary way to realize and fulfill our own global citizenship .
Nowadays ,terrorist acts suggest that world lacks comprehension ,and the divergence of religion and culture should be respect .Being respectful for the diversity is always.
